Abstract (en)
[origin: EP3460637A1] The present invention discloses an electronic device. The electronic device includes an OLED display, foam, and a film. The foam is located below the OLED display, and the film is located below the foam. Multiple bridge circuits are disposed on the film. Each bridge circuit includes a first branch and a second branch that are connected in parallel. The first branch includes a first resistor and a third resistor that are connected in series. The second branch includes a second resistor and a fourth resistor that are connected in series. The multiple bridge circuits are located on a same side of the film. At least one of the four resistors is bonded to the foam. At least one resistor is not bonded to the foam. The resistor that is bonded to the foam is made from a first material. A strain sensitivity coefficient of the first material is greater than 100. A film area in which the resistor that is bonded to the foam is located is covered by a second material, and the resistor that is not bonded to the foam is not covered by the second material. A Young's modulus of the second material is greater than 30. According to the present invention, the electronic device with a pressure sensor can be implemented.
